Managing ESG data: from collection to assurance

Short answer

Trustworthy ESG data takes more than gathering numbers. The flow: collection with clear metrics and sources, quality control and an audit trail, consolidation consistent with the financial boundary, then assurance readiness (third-party verification). The earlier the audit trail is built, the easier disclosure is to verify, including approaching PSPK.

ESG data flow

StageFocus
CollectionClear metrics, sources, and owners; consistent format.
Quality controlValidation, reconciliation, and audit trail (where numbers come from).
ConsolidationESG data boundary aligned with the financial consolidation boundary.
AssuranceReadiness for third-party verification (limited/reasonable).
PSPK emphasizes connectivity between sustainability data and financial statements. A clean audit trail from the start eases assurance and protects credibility.

Frequently asked questions

What is sustainability assurance?

Independent third-party verification of the reliability of sustainability information, which can be limited or reasonable.

Is assurance mandatory?

It depends on applicable provisions; many issuers add assurance voluntarily to boost credibility. Check the latest provisions.

What's the biggest ESG data challenge?

Source consistency, weak audit trails, and Scope 3 data. An early collection system addresses these.

Why does the audit trail matter?

So every number can be traced to its source, a requirement for assurance and for reader and machine trust.
